Haiku Stairs

The Haʻikū Stairs, also known as the Stairway to Heaven or Haʻikū Ladder, is a steep, steel step structure that provided pedestrian access to former U.S. Navy communication facilities on the island of Oʻahu, Hawaii. The more than 3,000 steps span along Oahu's Ko'olau mountain range. The pathway has been used as a hiking trail at various times but is not open to the public. The city council voted to remove the stairs in 2021.
